Abstract: The arrangement is used in a method for pumping a liquid / gaseous phase mixture from an underground reservoir to a process plant, in which the pump arrangement is positionable in a flow line running between the reservoir and the process plant. The arrangement comprises: a liquid / gas separator GS having an intake for receiving an input supply of the liquid / gaseous phase mixture, and arranged to deliver separated outputs of liquid and gas; a motor-driven liquid pump P arranged to receive the liquid output from the separator, and to discharge a pumped output of liquid; a jet pump 16 arranged to receive the pumped output of liquid, and to pass the liquid through the pump prior to discharge of the liquid e.g. into the production pipe 12, after undergoing a pressure reduction by the jet pump; and, a gas inlet to said jet pump which is communicable with the gas output of the separator whereby the gas can be ingested into the jet pump by the pressure reduction so as to co-mingle with the liquid and be movable with the discharge flow of liquid from the jet pump. The pumping system may be arranged above the reservoir on the sea bed (Fig. 5). <IMAGE>

Title: Protection circuit for a power supply within a TV receiver
Inventor: HOH KIAN PEE
IPC: H03K17/082
Filed: 1993-07-01
Abstract: A switch mode power supply or line output stage in a TV receiver has a power switching transistor TP10 connected in series with the primary winding of a transformer Tr and a current sensing resistor RP30. A line synchronized sawtooth generating circuit 3 provides a switching voltage for the transistor. Circuit means are provided between the sensing resistor RP30 and sawtooth generating circuit 3 such that if the voltage at the sensing resistor RP30 exceeds a threshold value, the circuit 3 is inhibited from generating the switching voltage Us. Additionally, a second threshold circuit may be connected to the sensing resistorwhich, when activated, shuts down the power supply unit of the TV receiver. The second threshold value lies beyond the first threshold value. Switching transistor TP10 is turned off without any delay when current through it exceeds a predetermined value. If current through the transistor is further increased, the power supply unit of the TV receiver is switched off by the second threshold circuit. <IMAGE>

Title: Modular electrical switch and switching assembly for industrial elevators
Inventor: QUINLAN RONALD D
IPC: H01H3/00
Filed: 1994-04-05
Abstract: A modular electrical switch provides a wiping action upon closing and opening thereof. A contact carrier 150 disposed within a housing carries a movable bridging contact 162 into engagement with stationary contacts 149. The contact carrier is guided by movable slide plates 166 disposed on either side thereof and movable along with the contact carrier as a contact assembly. The guide plates also provide pivot recesses for pivot bosses 152 of the contact carrier. The contact carrier 150 is constrained to linear motion up to the point of contact between the movable contact and the stationary contact by a cam trace in the housing; after contact between the movable contact and the stationary contact, the contact carrier reaches a pocket 168 defined by the cam trace, ceases linear movement and upwardly pivots to provide a wiping action between the movable contact and the stationary contact. Immediately upon reverse, pivoting and linear motion of the contact carrier provides a shearing action between the movable contact and the stationary contact. A plurality of such replaceable modular switches are utilised in a freight elevator interlock system for regulating the various doors and carriage of the freight elevator. A common sliding actuator (104, Fig. 9) responsive to the position of the doors and carriage actuate actuator legs 154 on the contact carriers 150 of the switches. <IMAGE>

Title: Controlling power supply for liquid crystal display
Inventor: ISHIYAMA HISANOBU
IPC: G05F1/56
Filed: 1994-07-20
Abstract: A power supply for a liquid crystal display device enables designs with lower power consumptions and higher display qualities. A first constant voltage is generated by an operational amplifier 6. A second voltage having a value independent of the first voltage is generated by current sources 8 and switches 9 and added to the first voltage to generate a regulated voltage Vreg. The regulated voltage Vreg is divided by a voltage divider 12 within a multi-value voltage generation portion. The impedances of outputs V2 and V4 are converted by n-type OP-amps, and the impedances of outputs V1 and V3 are converted by p-type OP-amps to enable charge transfer. Sources 8 and switches 9 may be MOS transistors which provide regulation against supply voltage and temperature variation. <IMAGE>

Patent GB-2295883-A (GB)
Title: Pneumatic valve
Inventor: FLETCHER RICHARD EDMOND
IPC: F16K11/10
Filed: 1995-10-05
Abstract: A valve comprises a chamber 20 having an inlet 21, an outlet 23 and an exhaust outlet/s 22. A valve member 13 is moveable between a first position in which it blocks communication between the outlet 23 and the exhaust outlet/s 22 and a second position in which it unblocks communication between the outlet and exhaust outlet. The valve member is a diaphragm with an aperture 33 through it. The diaphragm carries a secondary valve member 100 operable to block the aperture in the valve diaphragm. When pressure is applied to the inlet the diaphragm is held against seat 28 and fluid may pass the valve member 100 to the outlet. When the pressure in the outlet is higher than the inlet the valve member restricts fluid flow from the outlet to the inlet and so the diaphragm is lifted off seat 28 allowing fluid to pass from the outlet to the exhaust outlet. <IMAGE>
